Download or read book An Analysis of the Effect of Mutations in the Leader Region of the Threonine Operon of Escherichia Coli on Attenuation Or Transcription Termination written by Harlan Bernard Scott (II) and published by . This book was released on 1991 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The expression of the threonine operon of Escherichia coli is controlled by attenuation. An open translational reading frame in the leader region preceding the structural genes contains 21 codons with eight threonine and four isoleucine codons. The model for attenuation proposes that regulation depends on the translation of the 21 amino acid leader peptide. Oligonucleotide-directed mutagenesis was used to introduce mutations into the leader region. Thirty-nine mutants were isolated. The effects of individual mutations on regulation were studied by making fusions to the lacZ gene, reducing the plasmid copy number, and assaying for the $beta$-galactosidase activity. Five mutants with two frameshift mutations each were constructed. The double frameshift mutants changed the leader peptide in two ways. First, the mutants had differing numbers of threonine and isoleucine codons. Second, the mutants had the threonine and isoleucine codons changed to differing numbers of histidine codons. Changing three threonine and one isoleucine codons abolished regulation by excess threonine and isoleucine. The presence of two histidine codons derepressed the operon in a hisT::Km background. Three mutations that would be predicted to block the translation of the normal leader peptide were constructed. All three mutants showed loss of regulation. The attenuator in the leader region encodes a rho-independent terminator. The terminator consists of a stem-loop structure with six bases in the loop and eight basepairs in the stem. The stem-loop is followed by nine rU residues and preceded by six rA residues. Various mutations in the threonine attenuator were assayed for their effects on transcription termination efficiency. As the number of rU residues in the terminator decreased from eight to one, the termination efficiency decreased. As the number of rA residues preceding the stem decreased from eight to one, the termination efficiency slightly increased. The sequence of the loop was also found to have a slight affect on termination efficiency. The sequences distal to the rU residues, which were non-transcribed, also had a slight affect on termination efficiency. Finally, a combination of changes in the stem with a change either in the loop or sequences distal to the rU residues had an affect on termination efficiency.

Book excerpt: The motivation for us to conceive this series of volumes on regulation was mainly our belief that it would be fun, and at the same time productive, to approach the subject in a way that differs from that of other treatises. We thought it might be interesting and instructive for both author and reader-to examine a particular area of investigation in a framework of many different problems. Cutting across the traditional boundaries that have separated the subjects in past volumes on regulation is not an easy thing to do-not because it is difficult to think of what interesting topics should replace the old ones, but because it is difficult to find authors who are willing to write about areas outside those pursued in their own laboratories. Anyone who takes on the task of reviewing a broad area of interest must weave together its various parts by picking up the threads from many different laboratories, and attempt to produce a fabric with a meaningful design. Finding persons who are likely to succeed in such a task was the most difficult part of our job. In the first volume of this treatise, most of the chapters dealt with the mechanisms of The second volume involved a somewhat regulation of gene expression in microorganisms. broader area, spanning the prokaryotic-eukaryotic border. Topics ranged from phage mor phogenesis to the role of gradients in development. The last volume-Volume 3A-con cerned hormones, as does this volume-Volume 3B.
